You can probably very carefully heat the pin nock adapter just enough to loosen the glue if it's hot-melt. Then you could install CB Bushings and use G nocks or use regular Uni-nocks. That being said, the fact that you can't see the arrows in flight is actually a good thing. If you are concentrating on aiming and follow-through then you shouldn,t see the arrow anyway.

You may want to see how your arrows are flying with broadheads. If so have somebody else watch them and you just make the shot. Do you want to know where the arrow went? Ask yourself, Where was the pin when the bow went off.
